Abstract

The invention provides a dry-type transformer with a three-dimensional core. The dry-type transformer comprises high-voltage terminals, a lifting ring, low-voltage terminals, an upper clamping piece, a transformer body insulator, a coil, high-voltage tapping, a pull screw, a side bowing type fan, a core, a lower clamping piece and a transformer base, wherein the core is spliced into a three-dimensional equilateral triangle through three identical single frames; one end of the core is provided with the transformer body insulator; the upper clamping piece is arranged above the transformer body insulator; the high-voltage terminals and low-voltage terminals above the upper clamping piece are connected in a staggered mode; the lifting ring is arranged on one side of the upper clamping piece; the coil and the high-voltage tapping are arranged at the periphery of the core; one side of the core is provided with the pull screw; the lower clamping piece is arranged below the core; one side of the lower clamping piece is provided with the side bowing type fan; and the transformer base is arranged below the lower clamping piece. The dry-type transformer with the three-dimensional core has the advantages that the problems of imbalanced three-phase power supply, high magnetic resistance, high magnetizing current, high no-load loss and the like are effectively solved.

Description

technical field [0001] The invention relates to a transformer, in particular to a three-dimensional core dry-type transformer. Background technique [0002] At present, with the increasingly fierce market competition, the cost competition of medium and small transformer products has become one of the important aspects of market competition. Existing products have problems such as unbalanced three-phase power supply, large magnetic resistance, high excitation current and no-load loss. . Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a three-dimensional core dry-type transformer. [0004] The technical solution adopted by the present invention is: a three-dimensional core dry-type transformer, including high-voltage terminals, suspension rings, low-voltage terminals, upper clamps, body insulation, coils, high-voltage taps, pulling screws, side blowing fans, cores, The lower clamp, the transformer base, and the...
